Definitions

  • the present invention relates to a method according to the preamble of patent claim 1.
  • Modern intelligent Listelde terminals are program-controlled and with at least one Processor equipped that communicates with central units of the communication system.
  • Thousands or more end devices can be connected to large systems, whereby in Programs necessary for the handling of communication functions for each end device and data are stored. Often there are large amounts of program code and Data.
  • program code and Data In the course of the further development of the system or on the basis of operator-specific Configuration changes must include program code and / or data in the end devices, respectively be brought up to date in whole or in part.
  • program memory, Database central point
  • the update should take as little time as possible to to impair the operational readiness of the system - if at all - only for a short time.
  • the time factor is particularly important when a large number of devices with large Code and data amounts must be updated. Then there is often the problem of one the transmission capacity between the central Location and the devices to be updated.
  • a group is proposed in [1] via the public ISDN of participants or devices. Some of these devices are direct over ISDN can be connected to a central unit for supplying information. Another of these End devices are supplied by end devices already supplied with information. adversely with this system is that to identify the group membership a special in the Group code stored in terminals is required. This group code also works lost, the terminal can be reached from any device within the ISDN may be provided with invalid or blocking information.
  • the present invention is therefore based on the object of specifying a method which enables large amounts of program code and data (hereinafter briefly also called "information") within a very short time from a central point to a large number from decentralized points of the system and thereby transfer the available ones Optimal use of transmission capacity.
  • the distribution of the information according to the invention takes place in the manner of a chain reaction which is triggered from a central point of the system and then in successive Steps all peripheral parts of the system to be supplied with new information. This allows large amounts of identical information to be quickly sent to many peripheral devices Transfer jobs. Further advantages of the method will become apparent from the description below an embodiment can be seen.
  • the system in Figure 1 consists essentially of a central unit ZE, a switching part VT and a variety of peripheral units T1, T2, ... Tn
  • System operators can be configured from the central unit ZE. In particular let from there, configure the penpheric units T as required.
  • This is the central one Unit ZE via the switching part VT with the relevant peripheral units T1, T2, ... Tn connectable.
  • the penpher units T1, T2, ... Tn are also via the switching part VT can be connected to one another as required.
  • a digital communication system constructed according to this principle exists in accordance with FIG essentially from a switching part VT and a large number connected to the switching part VT Terminal devices EG. It is also connected to the switching part VT via a So interface (with two B channels at 64 kbit / s and a D channel at 16 kbit / s) a system manager SM connected.
  • a system manager SM a computer (personal computer) with large Storage capacity and can be used with a screen.
  • the switching part VT consists of a switching network SWU to the shadow groups SLMY1 ... SLMY3 are connected.
  • Each switching group SLMY is on the one hand over an 8 Mbit line with the switching network SWU and on the other hand each over an 8 Mbit line connected to three multiplexers MUX.
  • the switching group SLMY has one Coupler for switching the voice and voice coming from the switching network SWU Signaling channels (time slots) to the multiplexers.
  • the MUX multiplexers have one Coupler, which the voice and signaling channels of the switching groups SLMY connects the coming 8 Mbit line to the corresponding terminals EG.
  • the MUX multiplexers are controlled by the assigned switching group SLMY.
  • the Switch-through network SWU is a digital coupler with a switch-through connection serving control. This makes it possible to use any terminal devices on the ground floor Interconnection groups SLMY and the interconnection network SWU and exchange data and voice information over these connections. Furthermore, over an interface module SLB on the switch-through network SWU external lines, e.g. Analog or digital lines leading to the public network, such as exchange lines La, leased lines Lb and dedicated lines Ls connected, so that the terminals EG over the mediation part VT can also connect with external bodies.
  • the in the Drawing shown number of switching groups SLMY, multiplexer MUX and end devices EG is to be regarded as an example for the present explanation; Of course a different configuration of the communication system is also conceivable.
  • the terminals EG form the interface between the users and the communication system and provide the user with a large number, depending on the application more convenient features available.
  • the terminals EG for example for various inputs and outputs (such as one-touch dialing) a keyboard with program-controlled LCD (Liquid Cristal Display) lettering on.
  • LCD Liquid Cristal Display
  • each end device EG has its own processor, which means in an associated program or data memory stored software controls the relevant functions.
  • the software is referral software and operator software.
  • the mediation software controls everyone functions related to communication, such as monitoring and Switching through connections (voice channels) to the multiplexers MUX and the switching groups SLMY.
  • the operator software essentially controls the User interface with the keyboard and the screen.
  • the system manager SM forms the interface between the operator and the system. He is with the switching network via an So interface and an interface module SSB SWU connected and has a large database, which among other things the data and programs for the configuration of the switching groups SLMY and terminals EG contains.
  • the invention shows a way with which the transmission time in a large number of terminals EG without additional circuitry. especially without additional So interfaces can be reduced.
  • the reduction achieved is - as will be shown below - especially with a large number of terminals EG and with relatively large to be transmitted Amount of information considerable.
  • a relatively large amount e.g. 5 MByte
  • a charging procedure activated by this builds on the Switching network SWU, the switching unit SLMY1 and the multiplexer MUX1 Connection from the system manager SM to the first terminal EGn, through a system manager SM known device number is identified. Thereby on the connecting lines between the switching unit SLMY1 and the multiplexer MUX 1 or between the MUX 1 multiplexer and the selected terminal EGn occupy a free channel (time slot), so that between the system manager SM and the terminal EGn the transmission over a Point-point connection e.g. B. can take place with HDLC protocol.
  • the terminal Egn issues a readiness message to the system manager SM from whereupon the information is transmitted to the terminal EGn.
  • the loading procedure step is a terminal device, namely the terminal device EGn with the new ones Information supplied.
  • the system manager SM sets up a connection to the terminal EGn + 1 as described and supplies it with the new information.
  • the system manager SM instructs the terminal EGn to supply the terminal EGn + 2 with the new information previously obtained in the first step.
  • the terminal EGn establishes a data connection to the terminal EGn + 2 via the multiplexer MUX1, the switching unit SLMY1 and the switching network SWU and supplies it with the new information received in the first step from the system manager SM.
  • three terminals EG have already received the new information. The procedure can now be continued with further identical steps until all the terminals to be supplied with the information have received the new information.
  • Steps of the loading procedure Step no.
  • Channel receiver Number of end devices supplied 1 SM EGn 1 2 SM EGn + 1 3 EGn EGn + 2 3 SM EGn + 3 7 EGn EGn + 4 EGn + 1 EGn + 5 EGn + 2 EGn + 6 4 SM EGn + 7 15 EGn EGn + 8 ... ... ... ... EGn + 5 EGn + 13 EGn + 6 EGn + 14 5 31 6 63 7 127 8th 255 9 511 m 2 m -1
  • the system manager SM In order to monitor the "chain reaction" described, it can be provided that after every step from the terminal EG receiving the information to the System manager SM is issued, the system manager SM receiving or successful transmission of the information confirmed. The system manager SM can then do so can be controlled that the next step of the loading procedure is only initiated if the Confirmation has been received from the relevant end devices.
  • a concrete example shows the gain in transmission time achieved with this method following assumptions: An amount of information of 5 Mbytes should be transmitted to each terminal EG the effective transmission speed is 50 kBlt / sec. Further becomes a coordination time (time between the end of one order and the beginning of the next Order) of 2 sec between the system manager SM and a terminal EG. The time for the transfer of the entire amount of information from the system manager SM to a terminal EG or from one terminal EG to another terminal EG therefore approx. 800 sec (5 MByte: 50kbit / sec).
  • the described method can also be used if only a part of the to the Devices connected to the communication system must be supplied with new information. This requires an appropriately programmed loading procedure that enables the transfer of Information about selected devices initiated.
  • the method can also be used to supply end devices with new information are used, which do not belong to a communication system according to Fig.2, but from this can be reached via lines La, Lb and Ls.
  • the application of the method is not limited to communication systems.
  • the procedure can e.g. also use in a data network constructed according to the principle of FIG has a plurality of interconnectable computers, each from a server must be supplied with new data and / or programs.
